CVE-2023-35867 Vulnerability Summary

CVE-2023-35867: An improper handling of a malformed API answer packets to API clients in Bosch BT software products can allow an unauthenticated attacker to cause a Denial of Service (DoS) situation. To exploit this vulnerability an attacker has to replace an existing API server e.g. through Man-in-the-Middle attacks.

Assessing the Risk of CVE-2023-35867

Access Complexity Graph

The exploitability of CVE-2023-35867 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2023-35867

CVE-2023-35867 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2023-35867, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2023-35867, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2023-35867 has no significant impact on data confidentiality.
  • Integrity: None
    CVE-2023-35867 poses no threat to data integrity.
  • Availability: High
    CVE-2023-35867 can disrupt system operations, potentially causing complete denial of service (DoS).

Exploit Prediction Scoring System (EPSS)

The EPSS score estimates the probability that this vulnerability will be exploited in the near future.

EPSS Score: 0.086% (probability of exploit)

EPSS Percentile: 39.16% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 60.84% of others.
